Scientists have long thought that the rate with which mutations occur in the genome does not depend on cultural factors. The results of a current study suggest this may not be the case. A team of researchers from France and ...

Elevated levels of C-reactive protein, a marker of inflammatory disease, appear to be associated with increased risk of psychological distress and depression in the general population of adults in Denmark, according to a ...

Scientists have shed light on why some people are more susceptible to gout than others. A study has identified 18 new genetic variations that increase levels of uric acid in the blood, which is the main cause of the disease. ...

Scientists at the Gladstone Institutes have identified a novel mechanism by which a type of low-carb, low-calorie diet—called a "ketogenic diet"—could delay the effects of aging. This fundamental discovery reveals how ...

Mice bred to age too quickly seemed to have sipped from the fountain of youth after scientists at the University of Pittsburgh School of Medicine injected them with stem cell-like progenitor cells derived from the muscle ...

(PhysOrg.com) -- Researchers from the University of Sydney's Alzheimer's and Parkinson's Disease Laboratory have achieved a major breakthrough by finding the causes of Alzheimer's disease at a cellular level and thereby identifying ...

(AP) -- It's starting to get crowded in the 100-year-olds' club. Once virtually nonexistent, the world's population of centenarians is projected to reach nearly 6 million by midcentury. That's pushing the median age toward ...

While AIDS originally was seen as an adaptive immune disease, the research of Alan Landay, PhD, has contributed to a view of it as a cell driven-inflammation linked to immunosenescence—the gradual deterioration of the immune ...

With the aging of the population, the incidence of dementia is increasing. The most common type of dementia, Alzheimer's disease, accounts for more than 60% of all dementia cases. According to current estimates, nearly ...

Population ageing

Population ageing or population aging (see English spelling differences) occurs when the median age of a country or region rises. With the exception of 18 countries termed by the United Nations 'demographic outliers' (see the Ud 2005 Human Development Report) this process is taking place in every country and region across the globe.
